What a wonderful thread.
Thank you @egwarhammer for showing me this.
What I really want a mod like TS2's Monique PC. That mod had so many things but what I'm really interested in from using the PC are two things:
1- Open individual bank accounts for the sims. You deposit funds to that account from the household money so each sim can have his own account if needed. The great thing about these accounts that they were earning interest so they kinda acted like investments as well, the interest used to be paid on the account weekly. This is so good to put the extra cash to grow and also was a great way to separate the money of strangers living in the same house. So once a sim wants to move out he has his own cash.
2- Lottery. Yes there is one lottery mod right now but I am not liking it. With Monique's PC you can buy 4 different kind of lottery tickets for several periods. and by the end of every week a notification pops up whether your sim won or lost with each ticket he bought.
I really love to see this made for TS4.
